Officials said Monday that the investigation began after customers complained of rashes and other skin irritations from using the knockoff mascaras, lipsticks and eye shadows.

The seized products include bogus versions of cosmetics by Urban Decay, MAC, Kylie Cosmetics by Kylie Jenner and others. Officer Norma Eisenman says at least six people received citations during raids at 21 locations in the Santee Alley area last week.

Officials warn that if the price of a product seems too good to be true, it probably is.
